T aZZ whom it may concern:

Be it known that I, lVILLIAir SHEPH RD- SON, a subject of the King of Great Britain, and resident of the town of New Liskeard, in the district of Timiskaming, Province of Ontario, and Dominion of Canada, have in ented certain new and useful Improvements in Wood Saws, t which the following is a specification. y

This invention relates to improvements in portable saws, and the objects of the invention are to permit of the saw being readily transported to the place at which the timber is being cut, to provide means whereby the saw is readily adjusted and fed to the timber, to prevent the timber binding on the saw, to limit the motion of the pivoted frame carrying the saw,"to utilize only a single belt to drive the saw, and generally to adapt the several parts to better perform the functions required of them.

l l ith the above and other objects in view, the invention consists essentially of the improved construction particularly described and set forth in the following specification and accompanying drawings forming part of the same. 1

In the drawings: I

Figure 1 is a side elevation of a sleigh with the improved saw mounted thereon.

Figure 2 is a plan view of the same.

Figure 3 is an end elevation of the improved saw.

Figure is a fragmentary side elevation of the saw taken from the opposite side to that shown in Figure l. 7

Like characters of relerencerefer to like parts in the several figures.

Referring to the drawings, A represents a sleigh provided with the usual runners B operatively connected by the draw bar C, the body of thesleigh being provided atthe rear end thereof with a pair of vertical standards 10 and 11. braced by the straps 12 and 13, thereby giving the desired rigidity to the same.

These standards are arranged in pairs and the standards 11 are capped by a U-shaped member 14, the lower edges of the side members of which are adapted to coact with the frame 15, which is pivoted intermediate of its length to the standards 10.

T he downward motion of the frame 15 is also governed bythe stop members 16 which Specification of Letters Patent. Patented July 18, 1922. Application filed February 24, 1919. Seria1,1 To.12?8,885, V

are secured to the lower end of the standards 11.

The frame 15 is provided at the rear end with bearings 17 adapted torotatably sup port the spindle 18 which is providedintermediate of its length with a belt pulley 19, while one end of the spindle projects beyond the bearings and carries a circular saw 20.

This saw is provided with a guard 21 rigidly mounted on the standard 11 adjacent to the saw, so that the guard is stationary, and rotary motion is transmitted to the saw by the automatically tightened belt 24, which engages with the pulley 19 and passes around the driving pulley 25 carried by the crank shaft 26 of the prime mover 27.

This prime mover may be of any suitable type, such as a gasolene or other internal combustion engine, and also an electric motor or any suitable power may be advantageously employed.

- lhat end 7 saw 20 is provided with balance weights 28 constructed as boxes into which cement is run to obtain the proper balance of the frame, and'suitable hand grips 29 and 30 are provided whereby the operator may manually oscillate the frame 15 to feed the saw to or from the timber being cut.

Duringthis operation the belt 24 automatically tightens on the pulleys 19 and 25, owing to the fact that the frame 15 is oscillatedaboutits fulcrum point which is slightly higher than the center of the pulley 25, so that when the saw is being fed into the timber the belt tightens.

To prevent the belt 2% from becoming displaced, it will benoticed that the standards 11 are located on opposite sides of the same.

Below the saw 20 a bench or saw board 32 is located on which the logs D being out are placed, and to prevent longitudinal movement of the log a bracket 33 is mounted or attached to the standards 11 by means of the brace 33, the said bracket extending on both sides of the sleigh and being provided with an adjustable stop block 34: which may ot the frame 15 remote from the,

be changed to either side of the bracket and with which the end of the log engages. I

It will be readily seen that by this mode of attachment the bracket 33 can be readily removed whenthe sleigh is passed through a gate so that there will be no liabilityof bracket engaging with the gate post or the like when the sleigh is passing through such an opening or other narrow space. This bracket is also notched intermediate of its length so that while the saw 20 may be readily lowered to cut the log lying on'the saw board 32 there will be no liability of the said saw engaging with the bracket and inadvertently cutting or destroying the same.

A tool chest 35 is conveniently located adjacent to the saw and carries the usual spanners, etc.,- required for tightening or adjusting any of the members.

When the saw is in use, the sleigh is drawn by any usual draft, such as a team of horses, and the sleigh is driven to the pile of logs about to be cut and so positioned that the logs are readily fed to the saw. are fed to the saw, the operator elevates the hand grips 29 and 30 so feeding the saw 20 into the log and when the logs are thus cut, the operator depresses the said hand grips to elevate the saw and permit of another log being positioned.

After the pile of logs are sawed the sleigh is driven to the next pile so that the manual labor of feeding the saw is to a great extent eliminated, as the logs are not carried to the saw but on the contrary the saw is transported to the logs.

It will also be clear that the operator has the direct control over the saw 20 independent of the man who is feeding the saw and should there be any possibility of anything going wrong, the saw can be immediately elevated. It will be evident that since the balance weight 28 balances the weight of the saw 20 located on the opposite end of the frame 15, that the slightest pressureon the said frame by the operator of the saw will readily move the saw in the desired manner either to feed it to the log or to withdraw it therefrom.

From this description it will .be seen that I have invented a portable saw which can be advantageously utilized by farmers and the like and in which the several parts are readi As the logs 1y accessible for inspection, the construction of the saw being extremely cheap and not requiring any skilled labor to run the same. As many changes could be made in the above construction, and many apparently widely different embodiments of my invention, within the scope of .the claims, constructed without departing from the spirit or scope thereof, it is intended that all matter contained in the accompanying specification and drawings, shall be interpreted as illustrativeand not in a limiting sense.

What I claim as my invention is:

1. A saw comprising a pair of standards, a frame pivotally mounted to the standards, a saw on one end of the frame, belt means for rotating the saw, hand grips on the opposite ends of the frame to the saw, balance means attached to the frame adjacent to the hand grips, a pair of standards located on opposite sides of the belt adjacent to the saw, a U-shaped cap on one of said standards having arms designed to co-act with the frame, a pair of'stop members on the base of the second said standards, an adjacent bracket below the saw and a stop block on the bracket, as and for the purpose specified. I 2. A sawing machine comprising two pairs of vertical alined standards arranged with the standards of each pair spaced apart, a rectangular counter-balanced saw frame enclosing said standards including side bars pivoted to one pair of the standards, upper and lower stops on the other pair of standards adapted for engagement with said side bars, a transversely extending saw supporting shaft carried by the forward end of the frame, a pulley on said shaft alined with the space between the standards of each pair, and a drive belt engaged with the pulley passing between the standards of each pair and guided thereby. i

In witness whereof I have hereunto set my hand in the presence of two witnesses:
